Referring to fig. 1 and 2, a connector according to an embodiment of the present invention includes a PIN 100, a rubber core 200, a housing 300, and a magnet 400.

The rubber core 200 is coated on the outer side of the PIN 100; an accommodating cavity 310 is formed in the housing 300, the rubber core 200 is arranged in the accommodating cavity 310, and a socket 301 for communicating the accommodating cavity 310 with the outside is formed on the housing 300; magnet 400 is disposed within receiving cavity 310 and extends at least partially through socket 301 to protrude from receiving cavity 310.

For example, as shown in fig. 1 and fig. 2, a plurality of PIN PINs 100 are arranged in the rubber core 200, and the plurality of PIN PINs 100 may be arranged in the left-right direction; an accommodating cavity 310 is formed in the housing 300, the upper end of the housing 300 is provided with a plugging port 301 for communicating the accommodating cavity 310 with the outside, the lower end of the housing 300 is provided with a mounting port for communicating the accommodating cavity 310 with the outside, the PIN 100 extends along the up-down direction, and the upper end of the PIN 100 is a plugging end for connecting with other connectors; the magnet 400 is disposed in the accommodating chamber 310, and an upper end portion of the magnet 400 protrudes upward to protrude out of the accommodating chamber 310 through the socket 301. When the connectors are connected with each other, the magnet 400 penetrates through the plug interface 301 to extend out of the accommodating cavity 310, and then the parts of the magnets 400 extending out of the accommodating cavity 310 in the two connectors can be contacted with each other, so that the adsorption force between the magnets 400 of the two connectors is improved, and the connection firmness between the two connectors is further improved; meanwhile, the housing 300 is arranged, so that the rubber core 200 and the magnet 400 can be arranged in the accommodating cavity 310 of the housing 300, and then the housing 300 can protect the rubber core 200 and the magnet 400, and further the service life of the connector of the application is prolonged.

In some embodiments of the present invention, the abutting portion 320 is disposed on the housing 300, and the abutting portion 320 is located at an end of the housing 300 close to the socket 301, and the abutting portion 320 abuts against an end of the magnet 400 close to the socket 301, so as to block the magnet 400 from sliding out of the accommodating cavity 310. For example, as shown in fig. 1 and 2, two abutting portions 320 may be provided at the upper end of the housing 300 to extend inward, the two abutting portions 320 are arranged in the front-rear direction, and the abutting portions 320 abut against the upper end of the magnet 400. The abutting portion 320 can further limit the magnet 400 to prevent the magnet 400 from being separated from the receiving cavity 310 from the socket 301 of the housing 300.

Further, referring to fig. 1 and 2, a recess 410 and a protrusion 420 are disposed at an end of the magnet 400 close to the socket 301, the abutting portion 320 abuts against the recess 410, and the protrusion 420 penetrates through the socket

301 to protrude from the receiving cavity 310. Due to the arrangement of the groove portion 410, the abutting portion 320 can be located in the groove portion 410, and further, when the abutting portion 320 can limit the position of the magnet 400, the abutting portion 320 can be avoided from the magnet 400 of the other connector, so that the protruding portions 420 on the magnets 400 of the two connectors can be in contact with each other, and the firmness of connection between the two connectors is improved.

Further, the protrusions 420 are provided at least at both ends of the magnet 400 in the length direction. For example, as shown in fig. 1 and 2, the magnet 400 may extend in the left and right directions, and the protrusion portions 420 may be provided at both left and right ends of the upper end surface of the magnet 400, and the recess portion 410 may be located at the middle of the upper end surface of the magnet 400. The two ends of the magnet 400 along the length direction are two magnetic poles of the magnet 400, the magnetic force at the magnetic pole on the magnet 400 is stronger than the magnetic force at other parts on the magnet 400, and the protruding parts 420 are arranged at the two ends of the magnet 400 along the length direction, so that the firmness of connection between the two connectors can be enhanced.

Referring to fig. 1 and 4, when the connector is a male connector, the contact end of PIN 100 is located in accommodating cavity 310 of housing 300, and when the connector is a female connector, the contact end of PIN 100 extends out of accommodating cavity 310 of housing 300; therefore, when the male and female terminals are connected, the PIN 100 of the female terminal can be inserted into the receiving cavity 310 of the male terminal to contact the PIN 100 of the male terminal, and the protrusion 420 of the magnet 400 of the male terminal is in contact with the protrusion 420 of the magnet 400 of the female terminal.

In some embodiments of the present invention, the sidewall of the rubber core 200 is provided with a joint portion 220, the housing 300 is provided with a joint hole 330, and the joint portion 220 is disposed in the joint hole 330 to prevent the rubber core 200 from sliding out of the accommodating cavity 310. For example, as shown in fig. 2, four engaging portions 220 are circumferentially spaced on the outer side of the rubber core 200, and four engaging holes 330 are correspondingly circumferentially spaced on the housing 300. When the rubber core 200 is placed in the accommodating cavity 310, the clamping portion 220 can extend into the clamping hole 330, and then the rubber core 200 can be prevented from being separated from the accommodating cavity 310.

Further, the clamping portion 220 is provided with a guide surface 221, and the guide surface 221 gradually gets away from the middle of the rubber core 200 along the direction away from the insertion port 301.
